Product Description:

 1. Introduction:

Mica is a rigid substrate able to withstand very high temperatures and are suited for applications up to 500°F (260°C). Mica heating elements offer several distinct advantages over other flexible heater technologies, including extremely low leakage, lower material costs, and higher operating temperatures. Our mica heating element is made by detail order requirments.

Mica plate is made of mica paper with highperformance organic silicon resin. After heating and pressing, the mica plate can be made into rigid or flexible insulating plates. The mica content is about 90% and the organic silicon resin content is 10%.

2. Applications:

Typical applications of mica heating elements are air heaters, enclosure systems, food service equipment, process and packaging equipment.

 

3. Main features of Mica Parts:

Mica heating elements offer several distinct advantages over other flexible heater technologies, including extremely low leakage, lower material costs, and higher operating temperatures.

Q:What is the DMD insulation material?
DMD (Dacron / Mylar / Dacron) full name polyester film polyester fiber non-woven soft composite foil, is a two-layer polyester non-woven fabric in the middle of a layer of insulated polyester film composite made of three insulation materials.
Q:What insulating material is used for high voltage cables
Features: The rated voltage of the cable is 6kv. The long-term operating temperature of the cable is + 65 ° C. The minimum bend radius of the cable is 6 times the cable diameter.
Q:Who knows what are the ability of 1300 degrees above the high temperature, insulation materials?
Such as tungsten, molybdenum, tantalum, niobium, vanadium, chromium, titanium, zirconium and other refractory metals and rare earth metal borides, carbides, nitrides, silicides, phosphides and sulfides; the latter such as boron carbide, Silicon carbide, boron nitride, silicon nitride, boron phosphide, silicon phosphide and the like. The latter has a very important use, can be used as high temperature refractory materials (such as abrasive, mold, nozzle, high temperature thermocouple casing), heat-resistant materials (such as rocket structure components, nuclear engineering materials, electric components), electrical materials Such as high temperature thermocouple, ignition electrode), in addition to chemical resistance materials and hard materials.
Q:What is the thermal aging and electrical aging of insulating materials?
Insulation materials in electrical equipment during the operation, due to the long-term effects of various factors, there will be a series of irreversible physical and chemical changes, resulting in its electrical performance and mechanical properties decline, commonly known as aging. There are many factors that affect the aging of insulating materials. The main aging forms are environmental aging, heat aging and electrical aging.
Q:The role and definition of insulating materials
The main indicators affect the performance of insulating materials 1, insulation resistance, resistivity: resistance is the reciprocal of conductance, the resistivity is the resistance per unit volume. The smaller the conductivity of the material, the greater the resistance, the reciprocal relationship between the two, for the insulation material, always want the resistivity as high as possible. 2, the relative dielectric constant and dielectric loss tangent:
Q:What is the difference between insulation and pressure?
Insulation resistance is measured with an insulation resistance tester (10000V or less) or an insulation shaking table (2500V or less). Since the test voltage is low, many insulation defects are not easily found; the withstand voltage test test voltage is high and the high pressure equipment is easily found Insulation defects;
Q:What insulating materials are used for transformers
There are also NOMEX® insulation plates for the mat and the support structure. The insulation between high and low pressure is made of 0.76mm thick NOMEX® cardboard. Its impregnation process uses multiple VPI vacuum, pressure impregnation, high temperature drying (drying temperature of 180-190 ℃). At FPT, the highest voltage of this transformer is made to 34.5kV and the maximum capacity is 10000kVA. This technology is UL certified in the United States. Domestic transformer manufacturers use NOMEX® insulation materials and DuPont's manufacturing specifications (HV-1 or HV-2) and Reliatran Raytheon TM transformer technology standards such as the manufacture of H Type insulated SG-type dry-type transformers and the United States FPT's FB-type transformer has similarities, but the domestic product coil VPI impregnation process is different from the FPT company, it does not impregnate the entire transformer body, and only the coil impregnated. The whole body impregnated package integrity is good, but not only beautiful, but also in the processing must be done before the relevant product testing. Dipping paint is also easy to be filthy, relatively speaking in China the latter is more reasonable.
Q:What type of enameled wire and insulation material is used for the compressor
Small and medium-sized closed, semi-enclosed refrigeration compressors are used for the specific enameled wire specifically (QF) series.
Q:What are the commonly used insulating materials?
Commonly used inorganic insulation materials are: mica, asbestos, marble, porcelain, glass, sulfur and so on, which can be divided into inorganic insulating materials, organic insulating materials and mixed insulating materials.
Q:What insulating materials are used for high frequency transformers?
Where the water is mainly a resin and solvent or resin, oil and solvent composition, is based on polymer polymer, under certain conditions can be cured into an insulating film or insulation of the important insulation material, applied to high-frequency transformers After the surface, the solvent evaporates, the resin or the resin and the oil form a smooth film, showing the original pattern of the object. Easy to dry and durable, and can acid and oil.
